The Lowdown
Alright, Rusty here, switching to feet and knots.
Let’s be straight: Kennebunk Beach is looking at a real flat spell for the next 16 days. From Tuesday the 14th right through to Thursday the 23rd, it’s a tough stretch. The only window that’s got any real juice is Saturday the 25th.
Kennebunk Beach is a sheltered spot, consistent enough for intermediates, and the optimum swell is from the ENE. The water is a touch warmer than average for this time of year, sitting at 67°F.
For the first week and a half, the swell is a joke. We’re talking heights mostly under 3 feet, with periods all over the place but mostly short and weak. The combined energy is in the weak to moderate range – mostly under 100, rarely hitting 200. The wind is mostly cross or cross-on, with a few glassy moments on the 20th and 21st mornings, but with no swell, it’s a washout. The 24th sees a spike in energy up to 492 in the afternoon, but with a 3ft swell, a 7-second period, and a strong cross-on wind, it’s choppy and ugly – better for a kite than a surfboard.
The standout is Saturday the 25th. Morning and afternoon both look good. The swell is 5ft from the SE, with a period of 12 seconds dropping to 11 seconds – that’s real groundswell energy. The combined energy is strong to very strong: 630 in the morning, 445 in the afternoon. The wind is light and cross-off, keeping the surface clean. It’s not a perfect direction for the break, but it’s the best wave we’ll see in this whole forecast. Sunday the 26th morning is glassy but the swell is already back down to 3ft.
So if you’re keen, the call is clear: Saturday the 25th is your window. The rest of the time, it’s a flat spell.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
